Answer:
Here, we have:
P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084
P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238
P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385
P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272
Add up those above, then the probability that it will snow AT LEAST five of those days in February:
P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979
Hope this helps!

Answer:
$ 1,350
Step-by-step explanation:
i = (prt) / 100
p = $ 1,200 r = 2.5% t = 5 years
i = (1,200 x 2.5 x 5) / 100
i = $ 150
amount = p + i
= 150 + 1,200
= $ 1,350
An event that cannot happen is impossible
